New Thermobar Duplex Sizes

Thermoseal Group, manufacturer of Thermobar and Thermoflex warm edge spacers and leading UK insulated glass component supplier, has introduced new sizes to its range of Duplex fittings for Thermobar warm edge spacer.

Previously available in 11.5x15mm, 11.5x18mm, 15.5x15mm, and 15.5x18mm, the range of Thermobar Duplex centre keys and edge keys has been expanded to include fittings in 7.5x18mm and 9.5x18mm.All sizes are available in Black, Grey, and Neutral colours. The Duplex keys are used to produce a sealed unit with Georgian style features that has the appearance of being constructed from several individual glass units, when it is in fact just one.

Sales Director Mark Hickox comments: “Thermoseal Group is dedicated to extending the range of compatible fittings available for our premium quality products. The expansion of this range will benefit our customers by providing greater flexibility and choice when manufacturing warm edge units.

Over the past few years we have witnessed a growing demand for warm edge spacer, and we see this continuing to increase as manufacturers’ strive for ever higher Window Energy Ratings. With this in mind we are committed to meeting our customers’ requirements for warm edge products and the range of bespoke Thermobar fittings that we supply.

Thermobar Duplex fittings are tailor made for use with Thermobar warm edge spacer – fitted back to back on the centre keys inside the unit. Using this system allows the manufacturer to create a Georgian effect without the need to use a different type of internal glazing bar.”
